:'installed on any standard bike in minutes.' The motor
mounts on the fr0nt fork of the bike,:and transmits
power from the driving roller to the front wheel. The
!_ _motor speed isfinger-controlled by the throttle lever (15).
Rais!ng the roller engage lever (10} wil! lift the roller
off _the tir e, giving you the choice of operating as a
:bicycle,'.or asa motor bike, without ever dismounting to
do eitfter: _

HANDLING
Because of the ease of installation, and simplified con-
trois, the motor can be used on every type of bike, from
aten-speed racer to a three-wheeled adult tricycle.
ECONOMICAL _:"-
The motor runs up to 160 miles_per gallon (MPG) at an
averagecruising speed. . •
GREAT PERFORMANCE... PEDAL,- OR POWER
Since the moto_mounts on-yOur_own bike, a bike suited
to your needs, you have the best of two worlds. Motor
off, your. bike performs as_welt as it always did. Motor
on, you've added a wonderful new dimension to cycling,
without sacrifice.
UNIQUE CARBURETOR:.. AUTOMATIC •:CHOKE!
With=the: throttle lever closed, the carburetor choke is
._aut0matically activated, with nothing to fiddle with, as-
spring you of quick and easy starts. As you move the
throttle lever to.higher speeds; the choke turns itself
off at the "proper.time, without your having to even think
about it_i Patented; _of co_rse, There is=another choke
lever (][:1:).-but this is for useonly when the temperature
is extremely cold. "_:-j:_
FUEL LEVEL GAUGE
F:rom the slit on rear side of the engine shroud and
through the half transparent fuel tank •wall, the. fuel
level can easily be observed (18).
NOTE: To pour the fuel, keep front tire=and engine
straight ahead and fill fuel only up to the maxi-
mum level in the filler hole with this. position.
After pouring; close Tank Cap tightly.

INSTALLATION
a. First, remove the clamp stay (A&B KEY NOs31 and
33° FIG. 3 on Page 10) from the clamp bracket (A&B
KEY NOs 2 and 32, FIG. 3 on page 10), ([-2)
b. Hold the clamp brackets with both handsand placethe
motor unit on the front tire and clamp the front fork
loosely by the clamp stay (A&B).
c. Push the roller engagelever down all the way. (][-4)
d. Unscrew the front axle shaft nut (6), put the sub muf-
tier stay (KEY No. 2-23) onthe axle and replace the
bxle Shaft nut loosely. (I-5) Then, connect rubber
joint (8).
e. When size of the bicycle wheel is !ess than 23 inchs,
Iongger side of sub muffler pipe should be shortened
to fit. This can be accomplished by cutting with a
steel saw.
f. Apply recommended air pressure to tire. ;
g. Keep the clearance between the driving roller and tire
approximately 4mm(1/6 inJ by adjusting wing nut
on adjusting rod (5). Or you "mayuse thickness of the
• enclosed spanner (KEY No. 1-61) to get rough idea of
the clearance. (I-6) For riding on wet surface, smaller
:_ :_clearance then 4mm will help avoiding slipping of the
driving roller. " ....

h. Make sure no part of the motor touches the fender or
tire. Tignten screws on the clamp brackets A & B.
i, Tighten axle shaft nut (6), Connect sub muffler (7)
with rubber joint (8) and attache spring clips. ([-7)
j. Install throttle lever in convenient position on bicycle
handle bar. (1-8)
STARTING INSTRUCTIONS
1. BEFORE STARTING
The motor uses a fuel mix of 25 0arts regular gesoline
to 1 part two-cycle oil. The fuel shouldbe premixed
prior to pouring into the fuel tank (12), Itis recom-
mended that a quality two-cycle oil be used in the
fuel mix. Failure to mix oil wi_h gasoline will result
in seizure and severe damage to the motor.
2.
." _ :,'NOTE:
STARTING OPERATION
a. Before starting, push knobbed area (A) of Primer
Pump (20) several times by finger, until Fuel gets to
• Carburetor.
b. Push down the roller engage lever.' ([-9)
c, Push the throttle lever away from you (closed posi-
tion).
d. Pedal the bicycle at proper speed.
e. Pull the roller engage lever up to start the motor.
When the motor is cold, the throttle lever must be
placed at fully closed position for the carburetor's
pump:up action.
f. Keep pedaling until the motor starts,
NOTE: For the first run, a little longer pedaling
would be required n order to pump gas
into the carburetor.
g, After the motor starts, gradually open the throttle.
NOTE: As the motor has been equipped with the
choke-less carburetor,;the motor will start
if'the throttle lever is-positioned at idle.
For starting in cold weather, a little longer
pedaling is required_ ,When extremely cold
use special choke lever (17).
3. DRIVING INSTRUCTIONS
a, The bike speed is controlled by ithe throttle lever.
On the throttle lever there is als0 a "red" motor
stop switch (16) which wil! turn the. motor off
in a_qy position.
b, When climbing a steep hill some pedal-assistance
from you may be necessary, Use your bike's lower
gears if necessary. Remember, mopeds also need
assistance on steep hills, but they don't have the
gears you probably have on your own bike.
c. When slowing down, reduce speed with the throttle
"or disengage the driving roller off the wheel. In an
emergency stop, just use.your brakes hard, and the
motor will stall itself, Drive carefully at all times•
,d. To re-start after a sudden stop, just follow regular
starting procedures.
e, When going down a long slo;3e, do not use,engine
brake. Disengage the driving roller.
f. On bad. roads, or going cross-country, operate the
motor at- moderate speeds, foi" your own safety,
and the protection of the mo,:or.

MAINTENANCE AND ADJUSTMENT
SPARK PLUG
Always use the recommended spark plug (NGK BM-6
or the equivalent) and occasionally check the plug g_
which should be 0.6mm (0.023 _ 0.025 in.). Und_
normal circumstances the electrodes should be perfectl
dry and light brown in col or. If the electrodes are covert
with carbon or oil, the plug should be cleaned; either
solvent or by sand blasting. Be sure to remove all sotver
or grit before reinstalling the spark plug, ([-t0)
